aic7xxx problems?

[Eriksson Stig]

Hi

Maybe You can help me out with this one...
I have hp DLT connected to an adaptec SCSI board.

This is a part of dmesg output:
   scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.6
           <Adaptec (Compaq OEM) 3960D Ultra160 SCSI adapter>
           aic7899: Ultra160 Wide Channel A, SCSI Id=7, 32/253 SCBs

   scsi1 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.6
           <Adaptec (Compaq OEM) 3960D Ultra160 SCSI adapter>
           aic7899: Ultra160 Wide Channel B, SCSI Id=7, 32/253 SCBs

     Vendor: BNCHMARK  Model: DLT1              Rev: 5032
     Type:   Sequential-Access                  ANSI SCSI revision: 02

The "BNCHMARK DLT1" is actually a hp DLT.
When rewinding this tape, using "mt -f /dev/nst0 rewind" with a reasonable
amount of data on the tape (~2 Gigs), i get the following in
/var/log/messages:

This does not happen with small amount of data on the tape, only when
rewind takes a *long* time
